Default Korean 2560x1440 with 55hz over HDMI (updatet)


I like the korean 2560x1440 ips monitors, and because of this, I added a third one to my setup for 3 screen twinview (with a 660ti).

Because the first 2 monitors already occupy the dvi ports on my card I buyed a monitor with hdmi 1.4a port as the third (there aren't many models with display port).

Under windows it is possible to use the full resolution of the screen with a custom mode of 2560x1440 pixels with 55hz like you can see in this youtube video:

This are the working settings under windows:

I translated this to the following modeline:

Modeline "2560x1440_55R" 221.1088 2560 2608 2640 2720 1440 1443 1448 1478 +hsync -vsync

But if i now select this mode (after disabling some (all?) EDID checks) all 3 of my screens turn black and the system doesn't respond any more.

My xorg.conf
My Xorg.0.log

Any ideas what else i should try?
